Optical devices and methods of manufacture

Abstract

Optical devices and methods of manufacture are presented in which glass interposers are incorporated with optical devices. In some embodiments a method includes forming a first optical package and then bonding the first optical package to a first glass interposer. The first glass interposer may then be connected to a second interposer.
